nah he is fine. one the best balanced chars in my opinion except that he is a bit too slow. i did the black belt with him last saison btw
If he was faster he would be high tier man. His super armor and AP gain is already great along with his level 2 and level 3 is good enough. Faster with his AP gain and super armor? Naw he's fine now. After the recent patch he got what he needed. S*** his old crappy level 1 even got 2 buffs, cheaper AP and an confirm within itself like Isaac's like 1. Not the best of Level 1s but it got some pretty great buffs.
